DuPont FILMTEC™ BW30 PRO-4040 Brackish Water Reverse Osmosis Membrane Element (Direct Replacement for DOW FilmTec BW30-4040 & LC HR-4040 )

Fiberglassed Large Commercial Elements for Challenging Water Conditions

DuPont FILMTEC BW30 PRO-4040 (formerly DOW FIlmtec BW30-4040) membrane elements are an industry standard for reliable operation and production of high quality water in light industrial and drinking water applications. This element features the fouling resistance membrane chemistry (made in USA) and thicker feed spacer to lessen the impact of fouling in harsh water conditions as well as a fiberglassed shell, which is recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. For the most effective cleaning, the element may be cleaned over a wide pH range (pH 1 – 13).


FilmTec™ Brackish Water Reverse Osmosis 4" Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in medium-sized water treatment system that produce less than approximately 10 gpm (2300 L/h) of permeate. Our RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

Very Realistic… Might even fool your pet dog!
This is perfect for stuffed dogs I bought this for my daughter. My nine year olds friend has an emotional support stuffed dog and my youngest wanted one too. Everything is very realistic. Perfect enough food and bowl that when I put it down on the floor my Golden Doodle sniffed it for around 3 minutes before determining it wasn’t real. Excellent for kids that want to make their stuffie dog feel like they’re real. I definitely recommend this purchase.

Great Accessory for your Petzzz! Also handy for other plush toys.
This set of pretend dog toys is cute! It's a great way to let your (*adult?) children indulge their imagination with their favorite plush toys. They were designed for Perfect Petzzz brand toys, but will "fit" just fine for any plush animal about that size (a foot long or so). > Food Dish A small metal dish filled with plastic kibble pieces that are then hot-glued down. I consider the glue a slight disappointment - it would have been neat to have been able to strew the food pieces around the bowl like a real puppy would! But at the same time I understand wanting to reduce choking hazards for young children, or losing the food pieces during play. > Treats A pair of translucent plastic dog bone 'treats' designed to resemble rawhide. The design of these treats REALLY hit the nail on the head. They're VERY convincing, and I've had to stop myself from experimentally nibbling on them. Make sure that your real dog does not eat these! They do seem a bit ragged though, but that only lends to the realism - real rawhide treats also become ragged as the dog chews on them, right? > Chew Toy Rope A small piece of rope with knots tied on each end. The material appears to be either cotton or soft polyester, making the rope pleasant and soft in the hand. The braiding job on it is good, making it quite tough. Definitely overkill for pretend play, you could play a tiny game of tug-of-war with this. The ends past the knots fray wildly, but if anything this just adds to the effect.

Looks so real!
These are so much fun! I got it for my child to use with her stuffed animals. Out dogs frequently walk up to the bowl thinking it’s food for them. I like that the dog food is all glued together so that it’s not individual pieces since it’s a toddler that plays with it. The bone treats are impressively realistic. I’m very pleased with my purchase. Great product at a great price.
