Products for Paints and Textiles

We offer a comprehensive line of scientifically formulated products for paints and coatings, including Acids/Alkalis, Coagulants, Filter Aids, Anti-Chlorine, and Antiscalants. As well as New Product Development for custom applications.


The process water from paints and coatings is discharged (to the environment or municipal treatment plant) or recycled. ACS can provide customized neutralization reagents and equipment that adjust the pH down to acceptable limits for any end application.


Specific coagulants are employed to remove particulates, both soluble and insoluble. ACS can recommend specialized chemical blends that effectively remove solids and minimize sludge production.

Filter Aids

Filter aids include powder-based flocculants that help remove organics from effluent wastewater streams. Some of the filter aids we offer include: Bentonite Clay, Diatomaceous Earth, and Calcium Hydroxide Blend.


Membranes can be damaged by chlorine. Prior to water entering the membrane system, it’s imperative that all traces of chlorine be removed. This can be achieved through carbon filtration, or with a cost-effective anti-chlorine additive.


Antiscalants are chemicals introduced to the water stream prior to the purification process. Antiscalants help strengthen molecular bonds in order to facilitate higher recovery rates during the treatment process.

Media Filtration

Activated Carbon Filters are designed for chlorine and organics removal. From simple de-chlorination to critical dissolved organics removal, we offer a variety of activated carbon filters to meet individual application requirements. Dual Media Filters are typically used for turbidity and suspended solids removal. They may also be combined with a chemical feed system to effectively remove both iron and manganese. Multimedia Bed Filters consist of graded layers of media, including a coarse top layer of anthracite to remove the bulk of suspended solids, a finer second layer of sand, and a final layer of fine, dense garnet to polish the water to a high-clarity effluent.

Cartridge and Bag Filtration

Bag Filters are generally used to capture particles that exceed 50 microns in size. These filters can be cleaned or replaced. Cartridge Filters are generally used to capture particles from 0.1 micron to 100 micron in size. Cartridge filters contain more surface area than bag filters, although they can’t be cleaned and will need to be replaced. Their superior ability to capture particles makes them a suitable polishing filter before a process, or pre-filter for reverse osmosis equipment.

Ultrafiltration (UF)

This separation process is used in industry and research for purifying and concentrating macromolecular (103 – 106 Da) solutions. UF is used to treat surface water, ground water, seawater and waste water as either primary treatment or as pretreatment to reverse osmosis (RO) and Nanofiltration (NF). In some cases it replaces conventional pre-treatment. Other applications for UF include cheese manufacturing, process and waster water treatment, laboratory grade manufacturing, filtration of effluent from paper pulp mills and whey protein concentration.

Nanofiltration (NF)

NF systems have pore sizes from 1-10 nanometers, smaller than that used in Ultrafiltration, but slightly larger than used in the reverse osmosis process. They provide 50%-90% salt rejection. Advanced Chemical Systems uses these custom-built systems in a range of applications, including: water softening, maple syrup, flavor and fragrance industries, as well as purification of gas condensates, pesticides, bacteria, viruses and paint pigment removal.

Reverse Osmosis (RO) – See table below

RO is a membrane process wherein the membrane acts as a molecular filter to remove up to 99% of all dissolved minerals, bacteria, particles and organics. The membrane allows pure product water to flow through it, while rejecting the passage of impurities contained in the feed water. To limit the buildup of impurities on the RO membrane, a portion of the feed water containing the rejected impurities is flushed to drain continuously.
