Pulp Paper Waste Water - Industrial And Environmental Markets

Efficient removal of water in the liquid solids separation is key to overall use cost analysis. WaterSolve is keenly aware of the value and cost of producing solids to be removed from your site. WaterSolve dewatering polymers are used in a variety of equipment:


WaterSolve Polymers play a critical role in optimizing performance of filter belt presses. They produce the type of floc needed to maximize water release in the gravity section and prevent sludge extrusion in the compression zone. They also reduce the risk of filter blinding.

WaterSolve Polymers offer excellent floc qualities that allow for a tough floc required to handle the movement of the solids through the drum, while retaining the solids for optimum solids capture.

These polymers are designed for rapid floc formation needed to accomodate a relatively brief conditioning time. They also produce the tough floc required to withstand the high gravitational forces encountered. These polymers can increase recovery efficiencies and throughput and accomodate wider variations in sludge treatability.

WaterSolve polymers are formulated to accelerate free water release, speeding drainage and evaporation which significantly reduces drying time. They can dramatically increase surface loading rates and reduce the surface area required to dewater a given volume of sludge.

WaterSolve polymers offer excellent solids retention and high filtration efficiencies in dredging operations where the floc formation time is often limited and the time to specified cake dryness is critical.


WaterSolve high performance polymers promote formation of larger, heavier floc which settles faster and produces a denser sludge...and to maximize fines capture, producing a higher clarity supernatant that minimizes risk of recycled fines buildup.


In dissolved air flotation units, WaterSolve polymers and Inorganic Coagulants effectively flocculate biological solids from secondary clarifiers to produce masses to which rising bubbles can adhere. The surfactant properties of these polymers also serve to promote strong attachment of the air bubbles to the floc, promoting it's efficient flotation and removal.

Treatment plants that employ filtration prior to final discharge have found WaterSolve polymers a cost effective means for enhancing filter performance. We offer a wide variety of coagulant-grade and flocculant-grade polymers for this application, as well as a complete selection of inorganic coagulant/polymer blends.

WaterSolve polymer and inorganic coagulants offer superior performance characteristics that have proven especially beneficial to municipal sewage treatment plants employing enhanced primary clarification. In these applications, WaterSolve will test and formulate to accomplish the following:

Maximize removal of total suspended solids (TSS) and associated biological oxygen demand (BOD) in primary clarifiers
Enhance removal of color, turbidity, heavy metals, biological matter, and other primary pollutants
Allow increased throughput in primary clarifiers
Minimize solids loading on downstream systems, reducing costs, optimizing performance, and allowing increased throughput in biological treatment systems and secondary clarifiers

Your WaterSolve technical specialist can also develop and apply polymers designed to enhance performance of secondary clarifiers. These clarification aids have proven extremely effective in maximizing removal of the finely-dispersed, gelatinous biological solids generated in aeration systems. This has made them especially effective in responding to upset conditions to maintain secondary clarifier effluent quality and minimize problems in both upstream and downstream systems.

WaterSolve Inorganic Coagulants inactivate phosphorous by precipitating it as a metal phosphate. Ferric sulfate, in addition to inactivating phosphorus, controls sewage odors by precipitating soluble sulfide as iron sulfide. Aluminum coagulants stoichiometrically inactivate the highest rates of phosphorus, and produces a precipitate that does not re-dissolve under anoxic conditions.

WaterSolve Inorganics in conjunction with polymers or alone, offer highly effective emulsion breakers for treating waste with oil and grease.

WaterSolve offers a broad line of formulated and standard defoamers for Water and Wastewater treatment, and other industrial effluents.
