New Polymer Technology for Sand Control Treatments of Gas

20/4/2009· A long post-flush of gas is injected after the polymer treatment to re-saturate the formation around the wellbore and check gas injectivity. Seven wells have been treated so far with the following results: All treatments were successful in stopping sand production. The first treatment lasted about four years, after which it had to be renewed. All other treatments show long-term efficiency

3.1 Wastewater treatment technologies

Sand filters have been used for wastewater treatment purposes for at least a century in Latin America and the Caribbean. Two types of sand filters are commonly used: intermittent and recirculating. They differ mainly in the method of application of the wastewater. Intermittent filters are flooded with wastewater and then allowed to drain completely before the next application of wastewater. In

Rapid Sand Filtration SSWM Find tools for sustainable

Rapid sand filtration is a highly effective method to remove turbidity if it is correctly applied (BRIKKE & BREDERO 2003). Equally, solids formed during pre-treatment, i.e. coagulation-flocculation, are filtered.A well-operated RSF reduces turbidity to less than 1 NTN and often less than 0.1 NTU (WHO 1996).

Sand and Organic Filters Stormwatercenter.net

Sand filters are usually two-chambered stormwater treatment practices; the first chamber is for settling, and the second is a filter bed filled with sand or another filtering media. As stormwater flows into the first chamber, large particles settle out, and the finer particles and other pollutants are removed as stormwater flows through filtering media. There are several modifications of the

LNC — Desert Control

Our invention is a new way of mixing clay and water so when it is distributed to the soil, it envelopes each sand grain perfectly and spreads the clay perfectly in the sand in one go. Thus, when LNC is applied the sand turns into a sponge-like fabric that retains moisture/water and thereby holds the nutrients in the soil much better. Consequently you need less water for irrigation, and the
