Horizontal DAF The Vikas Horizontal DAF Process:
The Vikas Horizonatl DAF systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent. This recycle stream is then combined and mixed with incoming wastewater in an internal contact chamber where the dissolved air comes out of solution in the form of micron-sized bubbles that attach to the contaminants. The bubbles and contaminants rise to the surface and form a floating bed of material that is removed by a surface skimmer into an internal hopper for further handling.

Pulsuation Dampener

How Pulsation Dampeners Work
Pulsation dampeners operate on the principle that volume is inversely proportional to pressure. Compressed air or gas is introduced into the air chamber of the dampener to a specified pressure. The gas is entrapped by the elastomeric bladder, which prevents contact between the process fluid and compressed gas. (Without the bladder, the gas would dissolve into the fluid and cause product contamination). During pump discharge, fluid enters the wetted chamber of the dampener, displacing the bladder, compressing the gas and absorbing the shock. During pump shift, liquid pressure decreases, the dampener gas expands, pushing fluid back into the process line, eliminating up to 99% of system shock and pulsation.
Remove up to 99% of System Shock
Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging piping and system components.
Vikas Pulsation Dampeners and Surge Suppressors remove virtually all system shock, enhancing the performance and reliability of fluid flow in municipal, industrial, sanitary and chemical transfer applications.


How Vikas Dampener Works
Vikas Pulsation Dampeners use a compressed gas separated by a bladder from the process fluid like a shock absorber. During the pump's discharge stroke, fluid pressure displaces the bladder, compressing the trapped gas. During the pump's next cycle, fluid flow stops momentarily causing expansion of the compressed gas, forcing the bladder to push accumulated fluid back into the discharge line. This fills the void created by cycle shift and dampens pulsation up to 99%.
Protect Pumps, Valves and Instrumentation
•
• Protects pumps, piping, valves, fittings, meters and in-line instrumentation from damaging pulsations, cavitation, thermal expansion, hydraulic shock and water hammer.
• Prevent destructive pressure surges caused by pump startup and shutdown.
• Prevent hydraulic shock resulting from emergency valve closure and other equipment shutdown.
• Prevent agitation, foaming, splashing and degradation of product.
• Ensure accuracy, longevity and repeatability of flow meters and gauges.
• Ensure a smooth, steady flow in metering and chemical injection processes.
• Ensure uniform and continuous application in spraying and coating processes.
• Ensure proper measurement, flow and filling applications of food and pharmaceutical products.
• Ensure consistent flow when dosing, blending or proportioning process additives.
• Ensure a smooth transfer of viscous or abrasive fluids.
Protect Inlet System Components

Positive displacement pumps contain an inlet valve that alternately opens and closes, creating an acceleration and deceleration of fluid into the pump. Inlet Stabilizers minimize these pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet. The "J" Model air control allows for pressure or vacuum settings and is adjustable for suction lift or positive inlet pump conditions.
• Protect pumps, valves, diaphragms and pistons from excess stress and strain.
• Protect inlet system components from vibration and fatigue.
• Prevent premature system component failure and cavitation.
• Prevent gauge damage due to vibration.
• Ensure steady inlet flow conditions to extend diaphragm life.
• Ensure complete chamber fill to maximize component service life.
• Ensure accuracy of inlet side gauges.
Technical Specifications
Vikas Pulsation Dampeners, Surge Suppressors and Inlet Stabilizers come in a full range of chemically resistant materials for even the most corrosive applications. The simple, reliable design allows for quick installation and easy in-line maintenance. All housings are made at our workshop, and each unit is tested at design pressure or higher to assure proper function and leak-free operation.
Vikas Surge Suppressors use a compressed gas separated by a bladder from process fluid to suppress hydraulic surge or "water hammer" created by quick-closing valves, back surge, and pump startup and shutdown. Without suppression, shock waves created will continue to oscillate back and forth until dissipated by friction or system component failure.

Benefits of Surge Suppression:
• Protects pipes, valves, fittings, meters, and in-line instrumentation from destructive pulsations, surges, cavitation, thermal expansion, and water hammer.
• Creates steady and continuous flow when dosing, blending or proportioning additives.
• Ensures accuracy, longevity, and repeatability of in-line meters.
• Enables uniform application of material in spraying and coating systems.
• Reduces agitation, foaming, splashing and degradation of product.
• Provides liquid energy storage for emergency valve closure and other equipment shutdown.
• Reduces overall energy cost with continuous flow, rather than start/stop flow.
• Operates as a reservoir for make-up fluid.
