Side Stream Sand Filters
Side Stream Sand Filters are specially designed for higher flow rates per unit cross sectional area. In the conventional filters, water first hits the fine bed, where the suspended and turbid particles are trapped making imperative, the requirement of costly equipment like blower for the agitation of fine bed, so that the trapped particles are loosened and removed during the backwash.
Side Stream Sand Filters normally used for industrial cooling tower. Cooling Towers, by design, flush airborne contamination such as biocides, heat, slime or silt into the system, where they deposit on heat exchange surfaces. Suspended matter in the cooling water also supplies living microorganisms with a constant food source for sustaining life and multiplying. Shubahm provide suitable cooling tower Side Stream Sand Filters which can remove all the physical contamination from the water which affects the life and efficiency of the cooling towers system.
Advantages and Features of side stream sand filters:
Efficient Turbidity and TSS Removal Filtration up to 20 - 30 Microns FRP, CS, MSEP, SS Vessel available Pressure Vessel is also available Standard and effective media Low Pressure drop across the vessel Air scouring available for high flow pressure vessel Automatic Valves are provided as per customer need Manual, Semi Automatic and Automatic features are provided.
Technology Applications
The following are applications where the addition of a side stream filtration system can improve the water and energy efficiency of the system.
Systems for which the primary source of makeup water is a surface or other unclarified source.
Systems with difficult biological problems, even with the presence of a good biocide program.
Systems that are susceptible to fouling due to either the nature of the application or the environment in which they operate.
Systems where scaling deposits cause a loss of heat transfer.
Systems with high levels of solids buildup in the sump due to dirt and debris deposited by windy conditions.
Systems in which the heat exchangers require frequent mechanical cleaning
Technical description of by-pass filter for the industrial circulating water
Flow filter flow is designed according to 5% to 10% of the total circulation volume (the by-pass filter flow of the cooling water is designed by 10 % of the circulation volume and the by-pass filter flow of chilled water is designed by 5% of the circulation volume) and the filtration rate is designed by 20 — 3Smih according to water quality of the system. Specific to corrosive suspended solids of the circulating water system as well as the control, our technical support team has designed a variety of manual/automatic by-pass filtrating equipment in line with customer demand.
The characteristics of the filtration system
1. Manual or automatic control is available;
2. Water distributor is simple, uniform and reliable;
3. Finished water collector has high strength and long service life;
4. Easy to install. Only connect the inlet and outlet to the waste pipe when installing;
5. Less water consumption in backwash: A homogeneous filter is used, so that backwash cycle is extended and the total backwash water volume is greatly reduced;
6. High backwash efficiency: An advanced water collector is used, ensuring efficient backwash effect.
