MAKS 420 REVERSE OSMOSIS ANTISCALANT
GENERAL DESCRIPTION
MAKS 420 prevents silica fouling by a combination of anti-precipitation, anti-agglomeration and dispersancy processes. It allows plant operation with high reject brine silica levels. MAKS 420 is also an effective inhibitor for calcium salts and is not deactivated in the presence of iron.
PRINCIPLE USES
MAKS 420 is a synergistic blend of threshold antiscalants and dispersants, developed specifically as a membrane antifoulant for high silica feed-waters.
PRODUCT BENEFITS
- Effective silica and calcium salt antifoulant in all types of water
- Liquid product, safe and simple to handle
- Enables recovery rates to be maximized
- Compatible with all membrane types
- Effective over a wide pH range.
DOSAGE & FEEDING
The BIMAKS computer package will define the optimum chemical requirement for any given water quality. In calculating dosage rates, membrane manufacturer’s limits, product capability, operating parameters and feed water quality are all considered.
All calculations are made on the concentrated reject brine and utilize the predicted Langelier Saturation Index, or the Stiff and Davis Index where seawater and high salinity water is in use. Calcium, barium and strontium sulfate solubility’s are also calculated as is the dose of MAKS 420. . With high silica brines (180 – 240 mg/l) it is essential the correct level of MAKS 420 is present in the feed water at all times as silica fouled membranes are extremely difficult to clean.
Your BIMAKS representative will recommend the optimum dosage necessary to ensure maximum program performance according to your specific system parameters.
MAKS 420 needs to be fed continuously to the feed water. Dosing of the neat product is preferable.
MATERIALS: Storage and application equipment (pumps, lines) should be made of Stainless Steel 304, PE, PP, PU, Neoprene, Hypalon , Buna-N or Plasite 4300 and 7122. Do not use Viton or EPDM in contact with the neat product.
HANDLING-STORAGE-SHIPPING
As a standard precaution with all chemicals we recommend the use of personal protective equipments such as goggles and rubber gloves when handling. Consult the Material Safety Data Sheet as the only official source of Environmental and Safety information.
MAKS 420 can be stored for at least 24 months from date of shipping if kept in its original, unopened container and under normal warehouse conditions. Protect from freezing and from exposure to high temperature.
MAKS 420 is available in non-returnable containers of different sizes.
APPLICATION METHOD AND QUANTITY
The dosage quantity of the product changes according to the operating conditions and water chemistry of the system. BIMAKS representative will propose the appropriate dosage quantity to ensure maximum conditioning performance based on the distributed system parameters.
