Reuse / Recovery Plant
WSIs scalping plants are designed to utilize the river of water available in every city: The Sewer!
These plants are sited along sewer trunk lines and designed to draw wastewater from the sewer, treat to reuse water standards and either feed a reuse water distribution system or feed directly to major recycled water users, such as:
*Golf Courses
*Nurseries
*Vineyards
*Orchards
*Landscaping & Freeway Irrigation
*Fire Control, Suppression and Fighting
*Concrete Batching Plants
*Street Sweeping
*Cooling Systems
*Industrial Users and Industrial Cooling Applications
*Flushing toilets where approved by local codes
These systems are ecological assets to the communities they serve while providing an economical solution to Mega centralized plant expansions. The growing demand for water is driving the need to utilize every possible source, including recycled wastewater. These systems play an important role in urban infrastructure planning providing a means to produce and use recycled water locally while reducing the load on existing infrastructure and centralized wastewater plants. This significantly reduces energy and infrastructure costs. Why pump wastewater through miles of pipeline to treat at a centralized plant only to pump reclaimed water an equal distance back for utilization? Treat and Use at the Source!
Distributed water recycling plants are the future of urban water and wastewater infrastructure planning!
25,000 - 10,000,000

Dissolved Air Flotation
A major advantage of using a WSI DAF unit over a traditional settling clarifier is that the very small or light particles, which settle slowly by gravity, can be removed more completely and in a shorter time period while using a smaller footprint than existing settling clarifiers.
For example, the typical amount of suspended solids exiting a BCR (Bio Chip Reactor) range from 200-250mg/l TSS (Total Suspended Solids). The DAF unit, will remove these solids down to a range of 10mg/l TSS prior to final filtration. A percentage of the clean water coming from the front of the DAF unit is re-circulated and pressurized while adding dissolved oxygen and then discharging to a manifold located on the bottom of each DAF unit.
Such a design completely eliminates the concerns of sludge bulking problems that may happen in a secondary clarifier for both the suspended growth process and the attached growth system.
Compared to other older technologies, still being used today, the DAF unit is a very simple and efficient process.
WSI will design a DAF for almost any application ranging in sizes from 50 GPM to several thousand GPM meeting the most demanding requirements.
Give us a call and we can design just the right DAF for your project!
Automatic Polymer System
A feed pump is supplied to inject the polymer solution into the DAF unit. A polymer preparation system is used to fully hydrate or uncoil the polymer molecule in order to expose the maximum number of charge sites to the treatment process. The process of the polymer activation and blending system is to gently and thoroughly activate the polymer without damaging the fragile molecular chain. The polymer system is comprised of a neat polymer dispensing system, dilution, mixing, aging and solution injection systems The polymer system is designed to inject the 0.1% polymer solution at a dosage of 5 ppm.
Maintaining a uniform shear field of energy is vitally important to the polymer activation process. This polymer system is designed to apply the ultra-high mixing energy at the point of initial polymer and water contact to prevent the polymer from gelling or agglomeration. The non-mechanical high hydrodynamic shear energy which disperses the polymer into small particles is created by using a mixing educator.
The high velocity jet stream produces a strong suction in the mixing chamber of the mixing educator causing the neat polymer to be drawn through the suction port into the mixing chamber. The well mixed polymer is diffused into the aging tank. A pump is provided to recirculate the polymer in the aging tank and will switch to pump the well blended polymer to the polymer solution tank when the level drops in the solution tank. Polymer addition to the DAF unit is utilized to enhance the solids separation effectiveness.
Your polymer system will be sized to meet your plants process requirements.
Fiber Ball Filter
The fiber ball filter uses a highly porous synthetic material as the filter media. The fiber ball is made of terylene fiber and measures about 1 inch in diameter. The porosity of the fiber ball is 96% and the packing density is 0.77-1.03 lb/ft3.
During filtration, the fiber ball media layer exhibits the ideal straight "V" distribution with the help of gravity compression. The lower media layer is denser than the upper media layer. This kind of media layer configuration allows deeper penetration of the solid particles in the media layer and also produces better quality filtered effluent.
The advantages of fiber ball filter include:
1. High filtration rate
2. Better filtered effluent quality
3. More solid retaining capacity
4. More production rate per filtration cycle
5. Less backwash water usage
The fiber ball filter is ideal for applications such as:
* Wastewater reuse
* Tertiary treatment of industrial wastewater
* Injection water treatment for oil fields
* Make-up water treatment for boilers
* Recycling water for swimming pools
* Pretreatment for UF and RO membranes feed
These units are typically used as pre-treatment before a belt press or centrifuge, or to reduce disposal volume.
Gravity Thickener
WSI gravity thickening units provide continuous dewatering of various types of waste sludges by gravity drainage through a porous synthetic membrane, (belt). The belt is supported by a series of perforated foils.
Rotary Thickener
WSI's rotary thickening units consist of one or more stainless steel baskets, (or cells) in the shape of two truncated cones set base to base. Stainless steel screen or synthetic mesh is firmly affixed to the baskets providing the dewatering surface. The baskets are driven by a single variable speed drive assembly with sludge flow controlled by the use of sensors and a small PLC.
Twin Wire Press/Sludge Presse
'Water is removed from the incoming sludge by being "pressed out" under the influence of pressure. Typically, a wire mesh belt is used to allow the gravity flow of water out of the sludge while also providing structural strength. The system is designed so that the wire mesh belts converge in a wedge-shaped configuration to squeeze the bulk of the water from the sludge. The belts continue in an S-shaped flow path through rollers to further compress and dewater the sludge. WSI manufactures presses up to 3.5 meters in width.

Papagayo, Costa Rica
Due to rapid growth of the resort, a 500,000 gpd wastewater treatment facility was required to meet the construction schedule. This system was designed, fabricated and installed in only 4 months.
This modular, packaged system includes: flow equalization, SBR treatment, clean water storage and disinfection, as well as an aerobic sludge digester.
Seascape, Hawaii
The second phase expansion of the Seascape Development WWTP was completed in September, 2008. The plant features below grade Bio-Chip Reactor tanks and recessed Dissolved Air Flotation Cells to maintain the ocean views. The current capacity of the plant is 180,000 GPD. The third phase will expand the plant capacity to 250,000 GPD.
The Second Phase Expansion of the Waikoloa Village Wastewater Treatment Plant was completed in March, 2010. The project is composed of three phases, converting an existing Intermittent Cycle Extended Aeration Plant (ICEAS) plant with a rated capacity of 300,000 GPD to a Bio-Chip Reactor Plant with a rated capacity of 800,000 GPD. The system utilized the existing reactor tanks for the new Bio-Chip Reactor and included the addition of two DAFs, Influent Screening, grit removal, control systems, stand-by power generator, two digester tanks and centrifuge dewatering.
The retrofit has been installed in multiple phases to allow uninterrupted treatment of the existing wastewater flows. When the third phase is completed, the treatment capacity will be nearly 3 times the existing plant capacity, produce a higher quality effluent and occupy nearly the same footprint.
This project demonstrates WSIs ability to work with existing conditions and provide a cost savings solution utilizing existing infrastructure.
WSI managed the design and installation of a lift station being built for the Mountain Falls subdivision in Pahrump, Nevada. Ultimately, the Jane Avenue Lift Station will help transport wastewater for the development that will include 4,200 single-family homes, a day care center, a water park, a large recreational gymnasium, a casino and a church.
Ka'upulehu, Hawaii
The Kaupulehu WWTP was a fast track project that was designed, permitted, built, and started-up in 90 days. This plant was sized to meet the front end wastewater requirements of a new development. When the development expands a larger wastewater treatment plant will be installed. This skid mounted treatment plant can then be mobilized to another site or facility requiring immediate wastewater treatment.
