This process is called industrial wastewater treatment or pretreatment. Pretreatment with MK-801 significantly reduced SP induced hyperalgesia. Ammonia Fiber Expansion (AFEX) is a promising pretreatment with no inhibitory effect in resulting hydrolysate. This allows for preliminary sedimentation of suspended solids as a pretreatment process. Repeated but not single methamphetamine pretreatment resulted in a significantly increased freezing behavior. Germination of the seeds involves pretreatment to remove dormancy arising from the thick pericarp. Another pretreatment method is to pretreat hydrothermally. Pretreatment involves alternate wetting and drying of the seed. Septage is a by-product from the pretreatment of household wastewater (sewage) in a septic tank. Additional pretreatment of feed water is required to prevent excessive damage to the membrane units. Two common medications used in the pretreatment of RSI include Lidocaine and Atropine. Some have decreased sperm numbers as low as 10% of pretreatment values. Inositol pretreatment could reverse these effects. During pretreatment process, suspended particles in the sea water is removed. Polyethylene cannot be imprinted or bonded with adhesives without pretreatment.
