Water Treatment for Paper & Pulp Industry: Paper and Pulp chemical supplier and water treatment experts, Pt Lautan Luas Tbk, are Quantum Filtration Mediums partner and DMI-65® agent in Indonesia and South East Asia.
Lautan Luas supplies thousands of the best available, specialised products and chemicals that are used in the paper and pulp manufacturing industry. For over 20 years Lautan Luas has used and specified DMI-65® as the best solution for iron and manganese removal for industries including paper and pulp manufacturing.
Iron and Manganese at levels as low 0.3 and 0.5ppm respectively can create nuisance staining and spots on paper products. Where the best, highest quality paper and pulp products are required, removal of iron and manganese from the industrial use water source is paramount. The best manufactures of paper products in the world find in preferable to remove iron and manganese to undetectable levels, where possible. DMI-65® is a high performance and cost effective solution that can remove iron and manganese to less than 0.05mg/L.
In 2012 and 2013 Lautan Luas supplied DMI-65® as a key solution for Asia Pulp and Paper Groups water treatment plants at Pindo Deli, Indonesia.
APP Group’s water treatment plant at Pindo Deli 2, processes 33 million litres of water per day, for paper and pulp production. Eight filters, containing, two hundred and fifty tonnes of DMI-65®, remove iron and manganese to below the Indonesian Standard of <0.02ppm Fe and <0.05ppm Mn
IRON AND MANGANESE REMOVAL: Build up of iron and manganese in the filter system results in very high maintenance overheads, loss of production and potentially system failure. DMI-65® efficiently removes dissolved iron to the almost undetectable levels as low as 0.005mg/L and manganese to 0.001mg/L as well as particulate, effectively removing this risk.
REMOVAL OF TOTAL SUSPENDED SOLIDS AND TURBIDITY: The DMI-65® also provides the perfect filtration coefficient resulting in excellent mechanical filtration lowering total suspended solids (TSS) to less than 1mg/L and turbidity levels less than 1 NTU.
REDUCED COSTS: The total cost of the iron and manganese removal water filtration system is significantly less than alternative solutions, the effectiveness, but relative simplicity, of DMI- 65® based systems reduces the upfront capital expenditure on plant complexity as well as the ongoing operational expenditure in chemicals, power and backwash waste water recovery.
HIGH FLOW RATES: The infused technology of DMI-65® promotes the highest oxidation rate of any catalytic filtration media. This permits a significantly higher water flow rate to achieve the same level of iron and manganese removal. DMI-65 can operate at linear filtration velocities up to twice that of conventional media with a corresponding reduction in capital equipment costs.
HIGH LOAD CAPACITY: DMI-65® also has higher iron and manganese load capacity which can extend the duration of filter runs and the time between backwashing, thereby reducing downtime, operating expense and wastage.
REGENERATION NOT REQUIRED: The media operates with a continuous injection of sodium hypochlorite at low residual levels (0.1 to 0.3mg/L) which eliminates the need for Potassium Permanganate.
WIDE OPERATING ENVIRONMENT: Stable and satisfactory performance at pH 5.8 to 8.6 and a maximum operating temperature of 113° F (45°C) reduces the need for investment to alter the operating environment.
LONG LIFE: DMI-65® is not consumed in the process giving it an expected operational life of up to 10 years, providing considerable advantages over other processes or media. The media does not display a decaying capacity to do its catalytic work. Over the 5 to 10 year period, through many backwashing operations of the bed to remove retained solids, an attrition loss of the media occurs by contact between particles and mechanical abrasion.
