Industrial sediment filters are typically designed to treat waters with quality problems such as high turbidity (>20 NTU), or high TOC (>4 mg/L). A typical turbidity removal filter will include coagulation, flocculation and granular media filtration
Many water sources are turbid, containing suspended particles varying in concentration from a trace in deep wells to thousands of mg/L in some rivers. Suspended solids include fine sand, silt, clay, decomposed vegetation, bacteria, algae, and other microbiological organisms.
Most commercial, industrial and farm/irrigation applications require 0.5 to 1 NTU water quality to prevent turbidity-based fouling of membranes, heat transfer surfaces, ion exchange resins and irrigation nozzles. Turbidity removal is critical in these enviroments.

Filtering media, media depth, flow linear velocity, filter operational control and backwash method are essential parts in the design of commercial and industrial turbidity filters.
When deciding the right water treatment for your sediment filter, Watercore can help with a range of solutions that will improve the operational efficiency based on your particular needs.
Our commercial and industrial High Rate Sediment Filters up to 55 m3/h come with an integrated top-mount multiport automatic valve with microprocessor and methods to initiate the backwash:
The standard operation cycles in Watercore High Rate sediment filters are:
Critical systems and most industrial equipment require continuos operation which have no allowance for down-time periods for maintenance or fixing.
This is typical in industrial environments like water feeds for medium pressure boilers or reverse osmosis systems and is resolved with an automatic twin system where one unit always in service.
Watercore twin alternating sediment filters have been designed to provide a continuos water supply alternating the filters during backwash or whenever a maintenance task is required.
The most common measure of the amount of suspended solids in water is turbidity, which is a measure of the clarity of the water. Turbidity can be measured in many different ways but the most widely used is the nephelometric turbidity unit (NTU) which measures how much light is scattered by a water sample when placed in front of a light beam.
NTU cannot be used for colloids and particles smaller than 1 μm as they do not scatter light and are thus, not detected using turbidity measurements.
