The reduction of sediment, capture of solids and ultra-fine particulate greatly increase water quality. Clearflow’s patented Water Lynx Gel Block Flocculants were created to rapidly reduce Total Suspended Solids (TSS) through the process of flocculation. In this process, colloidal material clumps together become heavy and drop through the water column (sedimentation) leaving highly clarified water. Traditional methods for flocculation are very expensive. Make-down equipment requiring a freshwater source, costly power consumption, often troublesome pumping equipment, and complicated PLC control systems with instrumentation are used to ensure adequate dosing. While these system work, they are unnecessarily complicated and capital heavy.
TSS reduction is a multi-step process. Flocculation is followed by sedimentation, clarification or filtration. The Water Lynx Gel Block Flocculant can be used in conjunction with all of these processes. Clearflow offers our very own simple and cost-effective hybrid alternative. Sedimentation and filtration are combined using Treated Geo Jute which is placed in designed structures or existing channels prior to release into the environment.
Clearflow has eliminated the need for the high priced traditional flocculation system. Because we blend and age and package our flocculant at our facilities, it comes in a ready state form. Use it right out of the box. Simply install the gel blocks in-situ and after a brief hydration period, the block is fully active.
How it works
The Gel block uses flow dynamics along with particle size, shape, and density to release or strip flocculant. It is a passive process, completely self-dosing and self-limiting, dependent only on the characteristics of the water flowing around the block.
Why it works so well?
- Passive treatment
- Broad pH range 3-12
- Not temperature sensitive
- Easily stored
- Environmentally friendly with no harm to aquatic organisms
The Water Lynx Gel Block Flocculants (WLB’s) require flow to release flocculant. The velocity for optimal performance should be between 0.3m/s (1 foot/sec) and 1.5m/s (5 feet/sec). Placing the blocks in static water will have almost no effect. A single block can treat up to 20000 m3 (5.3 million US gallons) at 190 L/min (50 US gpm) of flow. For example, a 570 L/min (150 US gpm) flow rate with 1000 Nephelometric Turbidity Units (NTU’s) would require 3 WLB’s.
The solids content is limited to less than 1% or 10000 NTU’s. The blocks have an upper limit because they are self-dosing. At high solids content, above 1%, the potential release rate is overcome. A liquid flocculant is then required.
Water chemistry varies greatly and not all flocculants work in every instance. Therefore, Clearflow created 5 different types to handle a wide variety of applications. Selection of the ideal chemistry requires laboratory testing. In most cases, this is done free of charge and is completed within a short time.
Water Lynx Gel Block Flocculants can be custom made to fit any application. Typically, it is sold in 7.5 cm x 12.5 cm x 23 cm (3”x5”x9”) block form, weighing between 2– 2.5 kg (4.4 – 5.5 lbs) (type dependent). Water Lynx Gel Block Flocculants are packaged 6 blocks to a box and are an inventory item. No special shipping designation is required and customers worldwide have received them via traditional shipping companies without issue.
