Groundwater mapping and locally engaged water governance in a small island terrain: Case study of Karainagar island, Northern Sri Lanka

open access: yesWorld Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023
Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.

The nose is not enough: Multi‐site sampling is best for MRSP detection in dogs and households

open access: yesVeterinary Dermatology, Volume 33, Issue 6, Page 576-580, December 2022., 2022
Abstract Background Following recovery from meticillin‐resistant Staphylococcus pseudintermedius (MRSP) infection of any type, dogs may continue to carry MRSP asymptomatically on skin and mucosae, contributing to the spread of this multidrug‐resistant, veterinary hospital‐associated pathogen with zoonotic potential to others and into the environment ...

调相机除盐水系统设计问题分析与改进建议

open access: yesGongye shui chuli, 2022
换流站采用大型调相机作为无功补偿手段,可加快电压恢复速率,降低换相失败风险,保障电网安全稳定。双水内冷调相机是目前广泛应用的大型调相机类型,以除盐水作为其冷却介质。国内调相机工程中除盐水系统一般采用超滤+一级反渗透+二级反渗透+EDI的全膜法水处理工艺。国内首批建设的大型调相机除盐水系统运行过程中,存在除盐水系统来水不稳定、超滤装置与反渗透装置流量不匹配、除盐水泵没有互为备用、反渗透加碱效果不满足要求、转子冷却水补水加碱无必要等问题,会对除盐水系统的制水能力、产水品质、使用寿命 ...

Synchronous treatment of heavy metal ions and nitrate by nanoscale zero-valent iron (Fe0)(纳米级Fe0同步处理重金属离子与硝酸根的研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2008
纳米级零价铁(Fe0)同步处理Cu2+、Ni2+、Cr(VI)等重金属离子和硝酸根的实验中发现,硝酸盐对重金属离子的去除基本无影响,而不同重金属离子则对硝酸盐的去除有不同的影响.同步去除Cu2+和NO3-、Ni2+和NO3-时,与单独去除NO3-相比,Cu2+、Ni2+可以明显地提高硝酸盐的去除率和反应速度,并且Cu2+、Ni2+的初始浓度越高,NO3-的去除效果越好,反应速率常数kobs也越大.纳米级Fe0同步去除Cr(VI)和NO3-时,Cr(VI)阻碍了Fe0还原脱除硝酸盐反应的发生,当Cu2 ...

Ultrafast Catalytic Decomposition Reaction Using a ZIF‐67@Cellulose Nanofiber Composite‐Based Cobalt/ Nitrogen Co‐Doped Nanoporous Carbon for Water Treatment

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

Comparison of the in vitro antibiofilm activities of otic cleansers against canine otitis externa pathogens

open access: yesVeterinary Dermatology, Volume 36, Issue 2, Page 148-158, April 2025.
Background – Biofilm production by canine otitis externa (COE) pathogens and resistance development to multiple antimicrobials are commonly reported problems in veterinary practice. The use of adjuvants to disrupt biofilms may be a viable adjunctive therapy.

高铁酸盐预氧化、絮凝除藻的实验研究

open access: yesGongye shui chuli, 2003
采用高铁酸盐对湖泊、水库水进行预氧化、絮凝除藻, 对其除藻的影响因素及其与预氯化除藻效果进行了对比。结果表明, 采用高铁酸盐预氧化, 投加0.14mg/L就能明显提高聚合铝对含藻类水混凝的除藻率。1.4mg/L高铁酸盐预氧化与20mg/L聚合铝联用的除藻率是单纯投加40mg/L聚合铝的3倍;水样pH对含藻类水处理的影响, 除藻率pH5.0> pH7.5>pH10;延长高铁酸盐预氧化时间, 除藻率稍有增加, 但超过10min, 对除藻率影响不大;腐殖酸的存在会明显阻碍聚合铝的除藻效果 ...

电渗析-活性污泥法组合工艺处理高盐废水

open access: yesGongye shui chuli, 2014
采用电渗析-活性污泥法组合工艺对高盐废水进行处理。利用电渗析装置及含盐量较低的汲取液,将高盐废水中的盐分脱除,脱盐后的废水采用活性污泥法生化处理。经过5次更换汲取液,160 min电渗析处理后,废水中的盐由22 000 mg/L降至1 630 mg/L,除碳酸氢根离子脱除率接近70%外,废水中其他离子的脱除率均达到90%以上;脱盐过程中废水中的有机物含量基本不发生变化。脱盐后的废水利用活性污泥法处理,反应24 h内,COD去除率维持在85%左右。
