Above that, the gains in flow rate shrink fast and cloth life shortens. Membrane presses run a second stage at 1.5\u20132.0 MPa to compress the cake before discharge. The right number for your sludge is what the bench test confirms, not what the brochure says.<\/div>\n<\/details>\n<details>\n<summary>How long is a typical cycle?<\/summary>\n<div class=\"lw-faq-a\">Most chamber-press cycles run 20\u201360 minutes. The number depends on cake thickness, feed solids, conditioning, and the dryness target. A pilot on a real sample narrows the range considerably before you commit to a plate count and a chamber depth.<\/div>\n<\/details>\n<details>\n<summary>Does higher pressure always give drier cake?<\/summary>\n<div class=\"lw-faq-a\">No. Past the point where the cake reaches its compressibility limit, extra pressure returns very little dryness and costs cloth life, sealing work and energy. A bench test plots the curve so you can pick the operating point where each extra bar of pressure stops paying back.<\/div>\n<\/details>\n<details>\n<summary>Why does the same machine give different dryness on different sludge?<\/summary>\n<div class=\"lw-faq-a\">Cake dryness is a function of the sludge \u2014 particle size, compressibility, organic content and conditioning response \u2014 not just the machine. Two plants with the same name can have very different feeds. The bench test measures the achievable dryness on your sludge, with the conditioning the test settles on.<\/div>\n<\/details>\n<details>\n<summary>Can I improve dryness on an existing machine without buying new equipment?<\/summary>\n<div class=\"lw-faq-a\">Often, yes \u2014 by re-optimising the polymer, lengthening the air-blow, slowing the feed pump, or adding an inline membrane upgrade on the plates you already have. We will look at the existing cycle data first before suggesting a hardware change.<\/div>\n<\/details>\n<details>\n<summary>How do I compare two filter press quotes fairly?<\/summary>\n<div class=\"lw-faq-a\">Normalise on the same basis: filtration area, target dryness, cycle time at that dryness, polymer dose, installed power and the level of automation. Two quotes that look similar on the headline price often differ on at least one of these, and the difference usually shows up in the operating cost.<\/div>\n<\/details>\n<details>\n<summary>Do these parameters apply to belt filter presses and screw presses too?<\/summary>\n<div class=\"lw-faq-a\">No \u2014 belt and screw presses are gravity-and-shear technologies with a different set of controls (belt speed, screw speed, flocculation point). The selection page sets out which technology fits which feed, and the bench test is the link between the two worlds.<\/div>\n<\/details><\/div>\n<\/p><\/div>\n<\/section>\n<p>  <!-- ============ PAR-7 CTA BAND ============ --><\/p>\n<section class=\"lw-sec\" style=\"padding-top:0\">\n<div class=\"lw-container\">\n<div class=\"lw-band\">\n<p class=\"lw-kicker\" style=\"display:block\">Plan with the numbers<\/p>\n<h2>Talk to a Loway Engineer About Your Parameters<\/h2>\n<p class=\"lw-band-sub\">Send a sludge sample, share the data you have, or just tell us the dryness and throughput you need.
