Ecocote®

Ecocote® is a homogeneous precoat product comprised of inert microfine cellulose fibers. The individual fibers are effectively processed to create a flocced structure and enhance the hydraulic permeability of the product resulting in longer run times. Ecocote is designed to work in conjunction with Powdex® precoat resins or to be used by itself. These products are applied to cartridge filtration systems such as condensate filter demineralizers to combine the unit operations of fine filtration and ion exchange. Optimal performance is achieved when precoating on Aegis® polypropylene wound and DualGuard® precoat septa. The precoat products and the septa are designed to work together and along with the Powdex equipment provide the most uniformly distributed precoats to achieve desired performance and runlength. Ecocote is often applied as a top layer over a Powdex precoat to increase suspended solids filtration capacity and to enhance precoat integrity and prohibit precoat cracking. Ecocote may be precoated directly on the septa for a more economical approach when ion exchange capacity is not needed. Ecocote can also be mixed with any Graver Technologies’ precoat product at point of use to achieve additional benefits in certain operating conditions.

Frequenty Ask Questions

What are Heavy Metals?

Heavy metals are naturally occurring elements with high atomic weights and densities, typically greater than 5 g/cm³. They include lead, mercury, arsenic, and cadmium. They can be toxic even in trace amounts, accumulating in organisms and causing health risks.

What are the Problems with Heavy Metals in Water?

Heavy metals in water can cause severe health effects such as neurological damage, kidney failure, and cancer, even at low concentrations. They persist in ecosystems, bioaccumulate in the food chain, and disrupt aquatic life.

What are the Heavy Metal Parameters for Water?

Heavy metal parameters include concentration levels, toxicity thresholds, bioavailability, and the presence of specific metals like Pb, Cd, Hg, and Cr. These are regulated by agencies like the EPA and WHO to ensure water safety.

How do you Calculate Heavy Metal Concentration in Water?

Heavy metal concentration in water is measured using techniques like atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or colorimetric analysis. The results are expressed in micrograms per liter (µg/L) or milligrams per liter (mg/L).

What is the Permissible Limit of Heavy Metals in Water?

The permissible limits vary by a regulatory body, but for drinking water, the WHO and EPA set limits such as Lead (Pb) ≤ 0.01 mg/L, Mercury (Hg) ≤ 0.001 mg/L, and Cadmium (Cd) ≤ 0.003 mg/L.

What is the Mechanism of Heavy Metal Adsorption?

Heavy metal adsorption involves ion exchange, surface complexation, and precipitation on adsorbent materials like activated carbon, biochar, or nanomaterials, reducing metal ions from contaminated water. Adsorption efficiency depends on pH, temperature, and adsorbent type.
