Cooling Tower Bypass Filtration Rapid Sand Filter

Shallow sand filter Instruction of Side stream filter
Shallow Medium Filter  is a kind of high efficiency filter equipment in cutting down water turbidity, and purifying water. It uses silica sand asits filter medium. Under a certain pressure, the muddy water come through the granular or nongranular silica sand, which can efficiently hold back suspended solids, organisms, colloidal solids, micro-lives, chlorine, odour and heavy metal ions, etc.
It consists of several standard filter tank unit, with unique water distributor and water collector inside.automatic backwash valve can control all system’s backwash process.

Side stream filter Features
Shallow media filter can widely used at different application, such as water filtering, cooling water by-pass filtering, waster water treating, etc.
1. Shallow media filter has flexible modules, which can combined under actual flow rate, on-site area.
It is operated backwash automatically, with time control, differential pressure control. Each filter element start backwash one by one, while no need stop operation in backwash.
2. With smooth water allocation. High efficiency in backwash, water saving, only 30% water consumption of traditional one. Filter uses ASM filter media, which is easy wash.
3. With unique 48” ball filtering unit, and light weight for the whole system. The normal concrete base can used to place. Easy install, no need any boom equipment.
4. With good anti-corrosion feature.
5. With lost cost, but long lifetime.
6. Water quality:
inlet water turbidity <80mg/L, outlet quality reach <20mg/L
inlet water turbidity <20mg/L, outlet quality reach <5mg/L
7. Flow rate: it can treat 30-500m³/h

When to Consider Sidestream Filters

The installation of a sidestream filter is a capital expense, which may be hard to justify in most plants. Consider the following as indications that a plant should look into the possibility of installing a filter.

1.\tThe primary makeup is from an unclarified water source (river, sewage treatment, etc.) that is high in suspended

solids and/or iron.
2.\tThe system is having a difficult biological problem even though a good biocide program is in effect.
3.\tHeat exchangers are opening dirty even though a good antifoulant program is being used.
4.\tExcessive corrosion rates can be traced to fouling.
5.\tLoss of heat transfer is attributed to deposition rather than corrosion.
6.\tHigh levels of solids are building up in the sump.
7.\tHeat exchangers require frequent mechanical cleanings.
As stated, these are indicative only. By identifying potential threats to your systems and solutions to those threats, you can determine the paybacks of installing a sidestream filtration system. Often the payback is less time than you would think. This will vary widely from system to system; the final decision will always rest with a plant, and will always be decided on economic grounds.

Rapid Sand Filter Tank /pressure vessel for water treatment

Once a problem has been recognized, several benefits can result from the use of a sidestream filter. Obviously, not all of those listed below apply to all systems, and good judgment must be applied before making any claims. However, bearing that in mind, the following benefits can be realized:

1.\tSince solids are removed from the system, the corrosion inhibitor will lay down its protective film on clean rather

than dirty surfaces, thereby reducing corrosion rates and increasing equipment life.
2.\tWhen used with good chemical treatment, the filter will keep the system much cleaner, and, as a result, the need for mechanical cleaning of exchangers and sumps is reduced.
3.\tA cleaner system means better heat-transfer rates for longer periods of time.
4.\tIn some cases, the removal of suspended solids from the circulating water allows higher cycle.
5.\tLarge biological growths and dead organisms are removed with a sidestream filter. This reduces chlorine demand

and makes nonoxidizing biocides more effective.

sand filter is typically used for:

•\tIrrigation water
•\tStorm water
•\tCooling water
•\tSwimming pool water
•\tWater in fountains and other water features
•\tsand filter is your ideal choice for water filtration and purification.

How Sand Filter works?

Sand filter is a great water purification equipment which use sand as filter media to remove suspended solids for

irrigation water, cooling water, swimming pool water etc.

 sand filters use this simple but very effective method to give you the filtration you need to clean your water. Water

enters sand filter and is channeled to the top of the filter and falls on a bed of sand. Filtered water then exits through

laterals at the bottom of the filter and the trapped dirt in the sand is removed via periodic backwashing and infrequent

sand replacement. This sand filter is easy to install and very simple to maintain.
