The UltRATEC Sand Water Filtration System provides a reliable and affordable solution for removing suspended solids and impurities from water sources such as rivers, lakes, ponds, and wells. Using the natural filtration properties of sand, it improves water clarity without the need for chemicals or advanced technologies.

Sand filters are used as a step in the water filter process of water purification. There are three main types: rapid (gravity) sand filters, upward flow sand filters, and slow sand filters. All three methods are used extensively in the water industry throughout the world.

The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high-quality water free from pathogens, taste, and odor without the need for chemical aids. Sand filters can, apart from being used in water treatment plants, be used for water purification in singular households as they use materials which are available for most people.

Key Features:

• Made from corrosion-resistant plastic and stainless steel for durability
• Filter bed dimensions are 36" x 36" x 24" to accommodate fluctuating flow rates
• Graded silica sand filter media removes particles down to 5 microns
• Backwash system clears filter as needed using air scouring and water flushing
• Inlet and outlet ports include control valves for simple operation
• Flow meter monitors performance and notifies when backwashing is required
• Underbed stainless steel support grid distributes water evenly
• Skid frame assembly mounts entire unit as one portable piece

Benefits:

• Improves water quality for uses like irrigation, boiler feed, or drinking water
• Lower cost alternative to membrane filtration or carbon treatments
• Simple and reliable design requires minimal maintenance
• Over 50 years of proven performance in filtration applications
• Robust construction suitable for outdoor installation
• Easy to operate - just turn on water flow and backwash periodically

The UltRATEC Gravel Water Filtration System offers a cost-effective physical filtration option for pre-treating water prior to disinfection or additional filtration processes. Using multiple layers of carefully graded gravel and sand media, it harnesses the basic principles of surface filtration to remove suspended solids and particles from raw water sources.

Filter gravel is used as a support media to filter sand and coal in water filters. For maximum efficiency, filter gravel must possess the necessary attributes of hardness and be rounded rather than angular.

How it Works:

Water enters the bottom of the filtration tank and flows upwards through layers of washed gravel ranging from 3/8" to 1/4" in diameter. Smaller 1/8" gravel and filter sand rest above to capture finer sediments.

As water percolates through this multi-media filter, solids become trapped on the surfaces and in pore spaces between the gravel chips. This pre-treats water in a passive, gravity-driven process without chemicals or active components.

Key Features:

• 304 grade stainless steel tank for corrosion resistance
• Gravel support grate distributes flow evenly
• Inlet shut-off and drain valves for maintenance
• Flow meter monitors performance over time
• Filtered water collection trough
• Compact 48"x24" footprint for space-saving installation

Benefits:

• Improves turbidity and TSS removal prior to disinfection
• Gravel acts as a biological site for beneficial organisms
• Low cost compared to manufactured filter media
• Simple installation and operation require little training
• Self-cleaning process does not generate backwash water
• Durable construction suitable for outside placement

With the UltRATEC Gravel Filter, municipalities, camps, farms, and more can easily pre-treat raw surface waters economically and with minimal chemical usage. This natural filtration technique represents a reliable first stage of water treatment producing clearer water.

Applications include pre-filtration for wells, cisterns, irrigation sources, and more. Get clear, cleaner water through a hassle-free, gravity-driven process.

Filter Gravel is a hard, round, predominantly quartz aggregate. The filter gravel, like filter sand, contains hard durable particles with a slow breakdown rate. This helps to prolong filter media life.
