WATER TREATMENT  ::  ACID MINE DRAINAGE

Chemstream offers clients a combination of specialized chemicals and patented water treatment equipment to enhance efficiency and lower costs. Chemstream’s formal process ensures that your water treatment problem is handled in a thorough and professional manner from start to finish.

Treatment Program
Chemstream implements a comprehensive and staged water treatment program to make certain you are receiving the most effective results.

Water source/quality - Underground or mine pool water is generally oxygen-starved and has high levels of carbon dioxide, which increases acidity and chemical demand. Levels of dissolved metals will also need to be accounted for and precipitated in order to obtain compliant water.

Aeration - Water with elevated levels of carbon dioxide acidity can greatly benefit from aeration prior to chemical treatment. Off gassing the carbon dioxide will reduce the acidity of the water, thus reducing the consumption of alkaline material.

Treatment - Chemstream can supply liquid caustic sodas an alkaline treatment choice to effectively raise pH to achieve effluent standards. Chemstream also has a full line of flocculants and coagulants that can aid in the removal of suspended metals and/or clays. These products will decrease settling time allowing for a cleaner discharge.

Retention - Maximizing the surface area of a pond to increase the retention time of the water will allow for lower contaminates in the discharge. Chemstream can provide pond partitions built custom for your pond. Using pond partitions will also decrease the dissipation energy of the water allowing flocs to grow larger and entrain more particles.

Monitoring - Chemstream installs and maintains state-of-the-art systems that utilize pH sensors, PLC's and wireless router modems that allow the pH and other parameters to be viewed remotely on your computer. In addition, our system can increase or decrease chemical feed rates as the flow rate of the water varies. This promotes consistent water treatment results and clarified water that is in compliance.

Water Treatment Products
and Equipment

Chemstream offers a full line of innovative products and equipment to resolve various water treatment projects.

pH Adjustment

ChemLiquid 252

This innovative product is a powerful, highly alkaline enhanced liquid caustic soda that is designed to treat acid mine drainage. It rapidly elevates pH and precipitates iron, manganese and aluminum.

ChemLiquid 250

As a high quality, 25% sodium hydroxide solution, this product is extremely effective at raising pH and precipitating metals.

ChemLiquid 202

The 20% sodium hydroxide variation of ChemLiquid 252. Enhanced liquid caustic soda designed to treat acid mine drainage. Elevates pH and precipitates iron, manganese and aluminum.

ChemLiquid 200

As a high quality, 20% sodium hydroxide solution, this product is extremely effective at raising pH and precipitating metals

C-Cid 500

An environmentally-friendly product that will reduce elevated pH levels.

AlkaLime 380

Coagulants/Flocculants

EverFloc 200W

This coagulant is a concentrated liquid that offers rapid water clarification by agglomerating brown, red and gray clays. It has been proven to be extremely effective in clarifying turbidity from run-off water in a variety of applications.

Liqui-Floc

Chemstream offers several LiquiFloc products with differing charges that can target metals and/or clays. LiquiFloc is used after an alkaline treatment to increase settling and improve clarity. LiquiFloc can be applied as a liquid or as a gel log. The gel logs can be contained in a stainless steel basket that is a simple, yet effective way to dispense flocculant into a discharge water flow. The basket offers a long-lasting and inexpensive alternative to dispensing polymer.

Other Products

ChemProx 500/350

Chemstream offers both 50% and 35% hydrogen peroxide for treating acid mine drainage and waste water. With the correct water quality, hydrogen peroxide is extremely efficient and cost effective at targeting dissolved iron. When compared to lime, hydrogen peroxide can often times provide cost savings in as little as six months.

Permanganates

Chemstream also offers a wide range of potassium and sodium permanganate solutions that will help oxidize iron and manganese and often allow the customer to treat to a lower pH and use less alkaline product.
