Why Filter Sodium Hypochlorite?
Filtering of the sodium hypochlorite to remove heavy metals and suspended solids is required in almost every application. Typically, sodium hypochlorite used in drinking water treatment and laundry bleach packaged in small bottles such as 1 gallon must be filtered. Other typical applications that require filtered sodium hypochlorite include wastewater treatment applications and any sodium hypochlorite stored at the customer’s site in large tanks where accumulated suspended solids will precipitate with the heavy metals and settle to the bottom of the tanks. The only filtering method that will produce the required results for these circumstances is a system that uses a filter aid in conjunction with additives to the bleach to help complex the metals and suspended solids.
The typical filter aid is either perlite or diatomaceous earth. With a proper choice of filter aids and additives, it is possible to achieve maximum particle size of approximately 0.2 micron, and metal contents of < 0.5 PPM of iron, < 0.05 PPM of nickel and < 0.05 PPM of copper.
The Powell Sodium Hypochlorite Filter System is the only packaged system available that offers an engineered system with guaranteed performance with the correct materials of construction such as titanium for metal components and PVC and Teflon® as nonmetallic components.
Produce High Quality Sodium Hypochlorite
 |
The Powell Sodium Hypochlorite Filter System provides the highest level of sodium hypochlorite quality available in the market and can be used with any quality caustic to yield sodium hypochlorite that can be packaged for the household market using sealed bottles, in the drinking water industry or any other application required.
Standard sizes of filters are 100, 200 or 300 square feet. Any of the filters can be purchased with a reduced number of plates, which reduces the initial cost - for example, a 300 square feet filter supplied with 200 square feet of plate (17 instead of 23). Additional plates can be added as flow rate and capacity require.

The filter shell and pump are constructed of titanium with fiberglass precoat tank and PVC piping providing an expected service of 30 to 35 years minimum for major components of the system. All parts of the system are easily repaired and maintained. Typically the filter is inspected every 6 to 9 months depending on the type of operation, and the filter cloth is replaced every 12-18 months with minimal expense.
Powell can assist in the design of the complete system and provide all the required components except the site, building and installation labor.
