Evaluating Kelly Tanks Adsorption Sacks

Kelly Tanks' Adsorption Sacks are designed for on-site wastewater treatment, particularly for retaining solids while allowing effluent to filter and drain efficiently. They are commonly used for concrete washout and other wet waste management tasks on construction sites.

Performance and Effectiveness:

• In trials comparing Kelly Tanks' Adsorption Sacks to market alternatives, the sacks demonstrated superior performance in retaining solids without becoming quickly blocked or "blinded" by solids, a common issue with absorption-type liners.

• The sacks' design allows for a fast flow of effluent while maintaining effective retention of suspended solids (TSS), resulting in cleaner outflow water.

• Unlike many alternatives, which use basic builder’s sacks with felt liners (often allowing fast flow but poor solids retention), Kelly Tanks' sacks use an adsorption mechanism: solids attach to the surface of the liner and eventually drop into the sack, keeping the liner clear for continued filtration.

• The sacks have been found to be longer lasting than most alternatives, with each sack capable of handling up to 50 washes before needing replacement.

  
  

Practical Benefits:

• Simple to set up, use, and empty.

• Durable and robust with a small footprint, suitable for challenging site conditions.

• Can be used with frames to facilitate draining and pumping.

• Cost-effective: Reduces off-site disposal costs and the risk of pollution.

• Manual pH control is possible, supporting compliance with environmental standards.

  
  

Pricing:

• Sacks are available individually or in bulk, with significant discounts for larger orders (e.g., £20.00 + VAT per sack for pallet quantities).
